DETAILED DESCRIPTION

Before any independent embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the accompanying drawings. The invention is capable of other independent embodiments and of being practiced or of being carried out in various ways.

FIG. 1 illustrates a shower bar system 20 used with a showerhead 22 and a handshower 24. The shower bar system 20 is connectable to a water supply (e.g., household/residential, commercial, etc.). The illustrated shower bar system 20 generally includes a shower bar 26, an upper supply assembly 28, a transfer valve assembly 30, an angled hose connector 32, a bracket assembly 34 and a showerhead connection assembly 36.

The upper supply assembly 28, illustrated in section in FIG. 2 , includes a supply adapter 40, a mounting collar 44, an escutcheon 48, a trim sleeve 52, an upper supply bracket 56, a supply connector 60, and an inlet connector 64.

The supply adapter 40 includes an inlet port 68 with threads to allow the supply adapter 40 to be coupled to a water supply pipe P. The supply adapter 40 also includes an outlet port 72 through which water exits the supply adapter 40 and enters the upper supply bracket 56. The interior of the outlet port 72 has a shape (e.g., hexagonal) to allow the supply adapter 40 to be rotated about an axis by a tool with a complementary-shaped head to threadedly couple the supply adapter 40 to the water supply pipe P.

The upper supply bracket 56 receives the outlet end of the supply adapter 40 at one end and, at the other end, has an annular portion 74. One or more seals 76 (e.g., o-rings) are disposed on the supply adapter 40 to seal the connection between the supply adapter 40 and the upper supply bracket 56. Each seal 76 may serve to provide a seal between two members and/or a friction fit inhibiting relative movement between two members. In other embodiments (not shown), different types of seals and/or frictional members may be used in the shower bar system 20. Also, in other embodiments (not shown), the outlet end of the supply adapter 40 may receive the supply bracket 56.

In the illustrated embodiment, the supply adapter 40 and the upper supply bracket 56 are axially slidable relative to one another while maintaining the sealed connection. Such relative sliding movement between the supply adapter 40 and the upper supply bracket 56 accommodates different wall thicknesses and/or variations in the depth of an existing water supply pipe P relative to the exterior portion of a shower wall W. The distance between the outlet of the water supply pipe P and the outlet of the upper supply bracket 56 is adjustable.

The supply connector 60 is positioned at least partially in the upper supply bracket 56. The illustrated supply connector 60 is generally cylindrical in shape and is hollow so that water may flow from the upper supply bracket 56 to the inlet connector 64. External threads on the supply connector 60 threadedly couple the supply connector 60 to the upper supply bracket 56. The interior of the supply connector 60 has a shape (e.g., hexagonal) to allow the supply connector 60 to be rotated about an axis by a tool with a complementary-shaped head. A seal 76 is disposed on the supply connector 60 to seal the connection between the supply connector 60 and the upper supply bracket 56. The supply connector 60 includes a tapered nose portion having a tapered seal 94 which partially projects into the annular portion 74 to interface with the inlet connector 64 and seal the connection between the supply connector 60 and the inlet connector 64. In other embodiments (not shown), other types of mating engagements are possible, such as a protrusion of the inlet connector 64 in mating engagement with a corresponding recess of the supply connector 60.

The inlet connector 64 (see FIGS. 2-4 ) is disposed in the shower bar 26 approximately in a location at which the shower bar 26 is received in the annular portion 74 of the upper supply bracket 56. The inlet connector 64 defines a first cavity 80 and a second cavity 84. The first cavity 80 is fluidly connected to the supply connector 60 and allows water to flow from the supply connector 60 to a main supply pipe or tube 88. As used herein, the term “pipe” should be understood to collectively refer to any pipe, tube, other conduit, etc. capable of transporting fluid. The second cavity 84 allows water to pass from a first showerhead pipe 92 to a second showerhead pipe 96. The second showerhead pipe 96 is secured onto a fitting with a stainless steel clamp ring 82. The pipes 88, 92, 96 provide a waterway assembly for the shower bar system 20.

The upper supply bracket 56, illustrated in perspective in FIG. 5 , includes a first cylindrical section 100 and a second cylindrical section 104 for assembly, as described below in more detail. In some embodiments (e.g. the illustrated embodiment), the diameter of the second cylindrical section 104 is greater than the diameter of the first cylindrical section 100. A groove 108 is disposed between the first cylindrical section 100 and the second cylindrical section 104. The first cylindrical section 100 is threaded. As shown in FIG. 2 , the mounting collar 44 includes a circular opening 112 having a diameter approximately equal to the diameter of the upper supply bracket 56, and complementary threads are disposed on the circular opening 112, the purpose of which is explained below in more detail.

The illustrated shower bar 26 is constructed as a one piece pipe which begins at the showerhead connection assembly 36 (see FIG. 20 ), is coupled to the upper supply bracket 56 (see FIG. 6 ), and ends at the transfer valve assembly 30 (see FIG. 7 ). As best seen in FIG. 6 , the supply pipe 88, the first showerhead pipe 92, and the second showerhead pipe 96 are disposed in the interior of the shower bar 26 to provide a tube-in-tube assembly. The shower bar 26 has an opening 116 which corresponds to an opening 120 (see FIG. 5 ) in the annular portion 74 of the upper supply bracket 56. The shower bar 26 has an o-ring 124 or other sealing/coupling member on either side of the opening 116, corresponding to grooves 128 in the annular portion 74 of the upper supply bracket 56. Thus, when the shower bar 26 is inserted into annular portion 74 of the upper supply bracket 56, the o-rings 124 and grooves 128 cooperate to couple the shower bar 26 to the upper supply bracket 56. The o-rings 124 also act as a bearing to protect the finish of the shower bar 26 when the supply bracket 56 is assembled to the shower bar 26.

In other constructions (not shown), the upper supply bracket and shower bar 26 may be assembled in a different manner. For example, the annular portion 74 may be provided with a slot or opening to receive the shower bar 26 radially (rather than axially) into the annular portion 74. The annular portion 74 may be flexible and/or include a movable portion to open and allow the shower bar 26 to be inserted and then to close and retain the shower bar 26. The annular portion 74 may include a retaining arrangement (e.g., a clip, a snap, a fastener, etc.) (not shown) to hold the annular portion 74 in closed condition.

The supply pipe 88 and first showerhead pipe 92 are sized and configured such that the supply pipe 88 and first showerhead pipe or tube 92 do not touch each other or the shower bar 26 (see FIG. 6 ). Thus, a space 130 is provided between the inner surface of the shower bar 26 and the internal components (the supply pipe 88 and the first showerhead pipe or tube 92) which can inhibit thermal transfer between these components.

As shown in FIG. 2 , the supply pipe 88 is coupled to the first cavity 80 of the inlet connector 64 by brazing, soldering, welding, a swage fit, an interference fit, etc., and the first showerhead pipe 92 is coupled to the second cavity 84 of the inlet connector 64 in a similar manner. In the illustrated embodiment, the second showerhead pipe 96 is made of a flexible material, such as cross-linked polyethylene (PEX). The second showerhead pipe 96 is flexible so that it can be inserted into a curved portion of the shower bar 26. The second showerhead pipe 96 is coupled to a connection piece 132 by a crimping ring 136 (see FIG. 6 ), and the connection piece 132 is coupled to the second cavity 84 of the inlet connector 64 by brazing, soldering, welding, a swage fit, an interference fit, etc.

The showerhead 22 is coupled to the upper supply assembly 28 through the shower bar 26, shown in FIG. 1 , and the showerhead connection assembly 36. In the illustrated embodiment, the shower bar 26 is curved or arched. In alternative embodiments (not shown), the shower bar 26 may include a sharper curve or be otherwise bent (e.g., at a right angle), for example, to accommodate low ceilings, or can take any other desired shape.

The transfer valve assembly 30, illustrated in section in FIG. 8 , includes a diverter connector 140, a transfer valve body 144, a diverter stem 148, a contoured seal 152, a screw 156, a handle 160, a mounting collar 168, an escutcheon 172, a trim sleeve 176, and a check valve 180. The mounting collar 168, escutcheon 172, and trim sleeve 176 can be substantially identical to the mounting collar 44, escutcheon 48, and trim sleeve 52 described above in connection with the upper supply assembly 28, but this need not be the case.

The illustrated transfer valve body 144 includes a first arm 184, a second arm 188, a third arm 192, and a fourth arm 196 and defines an internal cavity 200. The diverter connector 140, illustrated in section in FIG. 9 , is coupled to the supply pipe 88 and to the first showerhead pipe 92. The diverter connector 140 is partially disposed in and coupled to the first arm 184 of the transfer valve body 144. The diverter connector 140 defines a first cavity 204, which receives a portion of the supply pipe 88 in the internal cavity 200, and a second cavity 208, which receives a portion of the first showerhead pipe 92. The supply pipe 88 and first showerhead pipe 92 may be welded, brazed, etc. to the diverter connector 140. The diverter connector 140 is shown coupled to the transfer valve body 144 using screws (see FIG. 19 ). In an alternative embodiment (not shown), the diverter connector 140 may be welded, brazed, etc. to the transfer valve body 144.

The illustrated diverter stem 148, shown in FIG. 10 and in section in FIG. 11 , defines a first cavity 212 for receiving the screw 156, a portion of the first cavity 212 being threaded. The diverter stem 148 is partially disposed within the transfer valve body 144. Two grooves 214 are shown formed on the diverter stem 148. Seals 76 are positioned in the grooves 214 to seal the diverter stem 148 and the transfer valve body 144. The diverter stem 148 defines a second cavity 216 through which water passes.

A clip 220, illustrated in FIG. 12 , is keyed, pressed onto and fits in a grooved portion of the diverter stem 148 to inhibit rearward movement of the diverter stem 148 in the transfer valve body 144. The clip 220 turns when the diverter stem 148 is turned. In the illustrated embodiment, the clip 220 acts as a bearing against the front surface of the transfer valve body 144. The clip 220 includes an opening to allow the clip 220 to be attached to the grooved portion of the diverter stem 148. The clip 220 helps maintain a proper clearance gap between the handle 160 and the transfer valve body 144. A portion of the clip 220 includes a flat surface or rib to assist in removal of the clip 220 from the diverter stem 148 during product service. The clip 220 can be removed by spreading the flat surfaces with a tool, such as pliers. In the illustrated embodiment, the clip 220 is made of plastic, but, in other embodiments, the clip 220 may be formed of another material, such as metal.

The diverter stem 148 is rotatable at least about 180 degrees within the transfer valve body 144. In a first position, the second cavity 216 is in communication with and receives water from the supply pipe 88 and operates to supply water to the first showerhead pipe 92. FIG. 13 illustrates the diverter stem 148 in the first position, showing the water flow to the first showerhead pipe 92. In a second position (e.g., 180 degrees from the first position), the second cavity 216 is in communication with and receives water from the supply pipe 88 and operates to supply water to the check valve 180. FIG. 14 illustrates the diverter stem 148 in the second position, showing the water flow to the check valve 180.

An alternative embodiment includes a third position, and, in the third position, the second cavity 216 is in communication with and receives water from the supply pipe 88 and operates to supply water to both the first showerhead pipe 92 and the check valve 180. FIG. 15 illustrates the diverter stem 148 in the third position, showing the water flow to the first showerhead pipe 92 and to the check valve 180.

The contoured seal 152, illustrated in FIG. 16 , is placed over an opening of the second cavity 216. The contoured seal 152 includes two protrusions 174 which are sized and configured to be inserted into corresponding slots on the diverter stem 148 in a seal pocket. The protrusions 174 assist in maintaining the position of the contoured seal 152 relative to the diverter stem 148 when the diverter stem 148 is rotated. The protrusions also prevent the contoured seal 152 from extruding or peeling into the outlets in the transfer valve body 144 when the contoured seal 152 moves across the outlets.

The diverter stem 148 includes an opening 178 to allow water pressure to press against the contoured seal 152 when water pressure is present in the second cavity 216. The water pressure against the contoured seal 152 assists in pressing and sealing the contoured seal 152 to the first showerhead pipe 92 or to the check valve 180, depending on the position of the diverter stem 148. When the diverter stem 148 is in the first position, the contoured seal 152 operates to shut off water flow to the check valve 180. When the diverter stem 148 is in the second position, the contoured seal 152 operates to shut off water flow to the first showerhead pipe 92.

The diverter stem 148 includes a groove 182 to allow a limited amount of water flow to the first showerhead pipe 92 and to the check valve 180 when the diverter stem 148 is between the first position and the second position so that the valve is not completely shut off in these positions. This may ensure that there is not cross flow between the hot and cold water supply lines and water pressure does not build up in a hot and cold water mixing valve (part of the household or commercial water supply system, not shown) which can effect operation of and/or damage the mixing valve. In some alternative embodiments, the contoured seal 152 may be sized and configured to allow water to escape only to the check valve 180 or only to the first showerhead pipe 92. Limiting the water flow when the diverter stem 148 is between the first and second positions encourages the user to position the diverter stem 148 in the first or second position.

The handle 160, best seen in section in FIG. 8 , is coupled to the diverter stem 148 by the screw 156 or by a bolt, other fastener or fastening method. In the illustrated embodiment, the screw 156 passes through a recess in the fourth arm 196. A decorative end cap 224 may be placed over a portion of the handle 160 to conceal the head of the screw 156.

The handle 160 and diverter stem 148 are configured such that, when the handle 160 rotates, the diverter stem 148 also rotates. The handle 160 includes a protrusion 232 which mates with a recess 236 (best seen in FIG. 17 ) on the transfer valve body 144. The protrusion 232 and the recess 236 cooperate to limit the range of rotation of the handle 160 and the diverter stem 148 to, for example, 180 degrees, and to define the first and second positions of the diverter stem 148. In other embodiments (not shown), the handle 160 and the diverter stem 148 may be rotatable to a greater or lesser degree.

In an alternative embodiment, the handle 160 defines a cavity to receive a separate pin. A spring surrounds a portion of the pin and serves to bias the pin towards the transfer valve body 144. A recess 234, as illustrated in FIG. 18 , at the each end of the range of rotation is defined on the transfer valve body 144. The spring-biased pin and recesses 234 cooperate to limit the range of rotation of the handle 160 and the diverter stem 148. One or more intermediate recesses 234 may be provided to, in cooperation with the pin, define the intermediate position(s) of the handle 160 and the diverter stem 148. The opening in the clip 220 provides clearance for the protrusion 232 or the spring-biased pin on the handle 160.

In the illustrated embodiment, the check valve 180 is disposed substantially in the third arm 192. The check valve 180 serves to prevent reversed/backflow of contaminated water into the shower bar system 20 and to the water supply. Backflow may be caused by a back siphon due to failure in the water supply system (e.g. water main or pipe breaks). Check valves or vacuum breakers are used in systems with a moveable water outlet, such as the handshower 24, that could be placed into a vessel or bath fixture containing contaminated water. The illustrated embodiment uses a commercially-available check valve 180, such as NEOPERL Model Number 31.4264.0, from NEOPERL, Inc., located in Waterbury, Conn. Referring to FIG. 8 , a groove 237 is defined on the third arm 192 so that a coupling nut 238 may be coupled to the third arm 192. In an alternative embodiment, threads may be provided on the third arm 192 so that the coupling nut 238 may be threadedly coupled to the third arm 192.

The second arm 188 includes a first cylindrical section 240 and a second cylindrical section 244, and, in the illustrated embodiment, the diameter of the second cylindrical section 244 is greater than the diameter of the first cylindrical section 240. A grooved or recessed portion 246 is disposed between the first cylindrical section 240 and the second cylindrical section 244. External threads are disposed on the first cylindrical section 240.

The illustrated transfer valve assembly 30 relies upon movement of the diverter stem 148 to different rotational positions to port fluid to and from the transfer valve assembly 30. Although the particular valve shape and configuration described and illustrated herein provides various advantages in performance, it should be understood that other types of valves can be used that perform the same and other functions. By way of example only, the illustrated transfer valve assembly 30 can instead take the form of a multi-port ball, plug, or spool valve with ports appropriately selected and positioned with respect to one another with a diverter stem 148 moved by the handle 160 to adjust fluid flow as generally described herein. Such alternative types of transfer valves fall within the spirit and scope of the present invention.

It should be understood that, in other embodiments (not shown), the shower bar system 20 may not include a transfer valve assembly. In such embodiments, the shower bar system 20 would include only one water dispensing device (e.g., a showerhead 22 or a handshower 24) such that transfer of water flow is not required.

The angled hose connector 32, illustrated in section in FIG. 19 , includes the coupling nut 238, a threaded pin 252, a bushing 256 and an elbow 260, all of which cooperate to define a passageway. The coupling nut 238 includes a tabbed portion 262 operable to couple the coupling nut 238 to the third arm 192 of the transfer valve body 144.

External threads are disposed on the threaded pin 252, and a hollow portion of the threaded pin 252 has a shaped (e.g. hexagonal) cutout to allow a tool with a complementary-shaped head to turn the threaded pin 252. The elbow 260 has internal threads to couple to the threaded pin 252. An end of the elbow 260 includes a groove 263. The illustrated elbow 260 is bent (from the inlet to the outlet) at an angle of, for example, 135 degrees, although greater and lesser angles are contemplated. In some embodiments, the angle can be between 95 degrees and 175 degrees. In other embodiments, the angle can be between 105 degrees and 165 degrees. In still other embodiments, the angle can be between 115 degrees and 155 degrees. The elbow 260 can rotate 360 degrees in either direction around the center axis of the bushing 256.

A hose 264 couples the angled hose connector 32 to the handshower 24. The illustrated hose 264 is constructed with plastic tubing to limit or prevent damage due to contact of the hose 264 with components of the shower bar system 20, the on/off valve V, etc. In addition, the elbow 260 assists in guiding the hose 264 away from the shower on/off valve V. The hose 264 is commercially available from a number of suppliers. The hose 264 includes a hose bushing 268 which is inserted onto a groove of the elbow 260 to couple the bushing 268 to the elbow 260. In an alternative embodiment (not shown), the hose bushing 268 may be threadedly coupled to the elbow 260. The hose 264 and the hose bushing 268 are sealed together (e.g., by a washer (not shown) pressed against the hose bushing by the elbow). The hose 264 is free to rotate within the hose bushing 268. In the illustrated embodiment, the hose bushing 268 is made of plastic, but, in an alternative embodiment, the hose bushing 268 may be formed of another material, such as metal.

In an alternative embodiment (not shown), the hose connector 32 may not be used. Instead, the hose 264 would be directly coupled to the transfer valve body 144. In yet another alternative embodiment (not shown), the check valve 180 may be positioned in the hose 264 instead of in the transfer valve body 144.

The handshower 24 is coupled to the hose 264 in a manner similar to the coupling between the elbow 260 to the hose 264. In the illustrated embodiment, the handshower 24 is similar to the handshower shown and described in U.S. Pat. No. 7,578,453, the entire contents of which are hereby incorporated by reference. It should be understood that, in other embodiments (not shown), a different handshower (not shown) may be used, or the shower bar system 20 may not include a handshower.

Referring back to FIG. 1 , the handshower 24, when not being held by the user, may be held on the shower bar 26 by the bracket assembly 34. The illustrated bracket assembly 34 is slidably supported on the shower bar 26 to adjust the position (e.g., the height) of the handshower 24. The construction of the shower bar 26 (encasing the supply pipe 88 and the first showerhead pipe 92) allows the bracket assembly 34 to easily slide up and down along and/or to pivot about the shower bar 26. The bracket assembly 34 may also allow the angle of the handshower 24 (about a horizontal axis and/or about a vertical axis) to be adjusted as desired by the user.

In the illustrated embodiment, the bracket assembly 34 is similar to the bracket assembly shown and described in U.S. Pat. No. 7,766,291, the entire contents of which are hereby incorporated by reference. It should be understood that, in other embodiments (not shown), a different bracket assembly (not shown) may be used with the handshower 24, if provided.

The showerhead connection assembly 36 (see FIG. 20 ) includes an end cap 272 and a showerhead adapter 276 to fluidly couple the second showerhead pipe 96 to the showerhead 22. The end cap 272 is sized such that a portion of the end cap 272 fits into the shower bar 26. The end cap 272 includes a cavity which allows water to pass through. A first end of the end cap 272 is flared to allow an installer to easily insert therein a tapered insert 280, which is coupled to the second showerhead pipe 96. The second showerhead pipe 96 is coupled to a fitting on an end of the tapered insert 280 by a stainless steel clamp ring 86. The tapered insert 280 inhibits, by way of a plastic split lock ring 90, the end of the second showerhead pipe 96 from being withdrawn or decoupled from the end cap 272. The split lock ring 90 is disposed in a groove in the outer surface of the tapered insert 280 and fits into a machined undercut in an inner surface of the end cap 272. To seal the connection between the end cap 272 and the second showerhead pipe 96, a seal 76 is disposed in the cavity of the end cap 272. Another seal member 76 is disposed on the exterior of the end cap 272 to secure the end cap 272 in the shower bar 26.

One end of the showerhead adapter 276 is threadedly (or otherwise) coupled to the end cap 272. The showerhead adapter 276 includes a flat portion which engages with the end cap 272. The flat portion also assists in keeping the location of the showerhead adapter 276 consistent with respect to the end cap 272. A seal 76 is disposed on the showerhead adapter 276 to seal the connection between the end cap 272 and the showerhead adapter 276. A portion of the hollow cavity of the showerhead adapter 276 has a shape (e.g. hexagonal) to provide for the showerhead adapter 276 to be rotated or turned about an axis by a tool with a complementary-shaped head. The other end of the showerhead adapter 276 is threaded to couple the showerhead 22 to the showerhead adapter 276.

The showerhead 22, shown in section in FIG. 21 , is threadedly coupled to the showerhead adapter 276. The illustrated showerhead 22 is Kohler Model K-13695, available commercially from Kohler, Co. of Kohler, Wis. It should be understood that, in other embodiments (not shown), a different showerhead (not shown) may be used, or the shower system may not include a showerhead (or showerhead connection assembly).

As mentioned above, the shower bar system 20 may be installed in new construction of a shower or bathing installation or retrofitted into an existing installation. Assembly of the shower bar system 20 may be as follows: the shower bar 26 is inserted into open annular portion 74 of the upper supply bracket 56, and the o-rings 124 engage the respective grooves 128. The supply connector 60 is then inserted and threaded into the upper supply bracket 56 so that the supply connector 60 is pressed into the first cavity 80 of the inlet connector 64 through openings 116, 120. The trim sleeve 52 and escutcheon 48 are then disposed on the second cylindrical section 104 of the upper supply bracket 56.

To assemble the transfer valve assembly 30, the diverter stem 148 is inserted into the second arm 188 of the transfer valve body 144. The forward end of the diverter stem 148 projects from the fourth arm 196, and the clip 220 is coupled to the diverter stem 148 to prevent it from moving rearwardly in the transfer valve body 144. The handle 160 is coupled in the proper orientation (with the protrusion 232 substantially received in the recess 236) to the diverter stem 148. The end cap 224 is coupled to the end of the handle 160. The trim sleeve 176 and escutcheon 172 are disposed on the second arm 188 of the transfer valve body 144, and the mounting collar 168 is threaded onto the second arm 188.

The diverter connector 140, with the attached supply pipe 88 and first showerhead pipe 92, is coupled to the first arm 184 of the transfer valve body 144. The lower end of the shower bar 26 is received in the annular space between the diverter connector 140 and the first arm 184 and coupled to the transfer valve body 144 (e.g., by welding, brazing, etc.).

The check valve 180 is inserted into the third arm 192 and is held in place by a friction fit. To couple the angled connector 32 to the transfer valve assembly 30, the coupling nut 238 is then positioned onto the third arm 192 of the transfer valve body 144 with the tabbed portion of the coupling nut 238 received in the groove on the third arm 144. The angled hose connector 32 also helps contain the check valve 180 in the third arm 192. The hose 268 is coupled to the angled connector 32, and the handshower 24 is coupled to the hose 268. In an alternative embodiment, the third arm 192 includes a groove disposed in the interior thereof for receiving a flange or rib disposed on the check valve 180 to help maintain the check valve 180 in position when water is flowing.

To fix the upper supply bracket 56 to the shower wall W (see FIG. 2 ), a first hole, having a diameter approximately equal to the diameter of the first cylindrical section 100 of the upper supply bracket 56, is made in the wall W. A second hole and a third hole are made in the wall W, and the mounting collar 44 is coupled to the wall W using fasteners (e.g., toggle bolts and screws, etc.), disposed through the second and third holes. In an alternative embodiment, the mounting collar 44 is not coupled to the wall W until after the upper supply bracket 56 is coupled to the mounting collar 44. In an alternative embodiment, toggle screws or washers are placed between the mounting collar 44 and the shower wall W to distribute some or all of any pulling forces that may occur. The supply adapter 40 is threadedly coupled to the water supply pipe P.

The outlet end of the supply adapter 40 is received in the upper supply bracket 56 as the first cylindrical section 100 of the upper supply bracket 56 is inserted into the circular opening 112 of the mounting collar 44. The upper supply bracket 56 is moved (e.g., slid) along the supply adapter to the appropriate position based upon the distance between the outlet of the water supply pipe P (behind the wall W) and desired position of the shower bar 26 (in front of the wall W). The upper supply bracket 56 and supply adapter 40 are extended (e.g., telescoped outwardly) to accommodate a larger distance (e.g., because the outlet of the water supply pipe P is farther from the wall W) or are retracted (e.g., telescoped inwardly) to accommodate a shorter distance (e.g., because the outlet of the water supply pipe P is closer to the wall W).

The upper supply bracket 56 and the mounting collar 44 are threadedly coupled together. The mounting collar 44 and upper supply bracket 56 bear any force applied to the shower bar system 20, rather than such force being applied to the water supply pipe P. In an alternative embodiment, a tabbed portion of the mounting collar 44 snaps into the groove 108 of the upper supply bracket 56 to secure the supply bracket 56 to the mounting collar 44.

The trim sleeve 52 is then moved (e.g., slid) towards the wall until a tabbed portion of the trim sleeve 52 snaps into a grooved portion 278 of the mounting collar 44. The escutcheon 48 is moved (e.g., slid) towards the wall W until the outer portion of the escutcheon 48 contacts the wall W. The escutcheon 48 is generally held in place by friction and may include a frictional member 76 to assist in holding the escutcheon 48 on the trim sleeve 52.

The mounting collar 168 on the transfer valve body 144 may be coupled to the wall W in a similar manner. Two holes are made in the wall W, and the mounting collar 168 is coupled to the wall W using toggle bolts and screws, etc., placed through the holes. The trim sleeve 176 and the escutcheon 172 are positionable to provide for coupling of the mounting collar 168 to the wall W and, thereafter, to cover and conceal the connection.

The size of the waterway from the supply adapter 40 to the transfer valve 30 and from the transfer valve 30 to the showerhead adapter 276 is designed to allow sufficient water flow to maintain spray performance on larger showerheads 22 and handshowers 24, even at low supply pressures. In the illustrated embodiments, the waterway has, for example, a minimum 0.300 inch diameter or 0.071 square inch cross-sectional opening.

In the United States, the outlet of the water supply pipe P for the shower is usually positioned about 6 to 7 feet above the floor of the installation, and the shower bar system 20 is installed in the first configuration, described above. However, in other countries (e.g., in Europe or in Asia), the outlet of the water supply pipe P may be at a lower height, for example, at about waist level (e.g., 3 to 4 feet above the floor of the installation). In an alternative, second configuration, illustrated in FIGS. 22-23 , the shower bar system 20 may be modified to accommodate an installation in which the water supply pipe is at a lower height.

For example, in the second configuration, the diverter stem 148 is modified to define (see FIG. 22 ) a hole 284 on the end of the diverter stem 148 (closest to the wall W) (see also FIGS. 24-25 ). The transfer valve assembly 30 is coupled to the lower water supply pipe P in a manner similar to the connection of the upper supply bracket 56, in the first configuration described above. The supply adapter 40 is attached to the lower water supply pipe P and inserted into the second arm 188 of the transfer valve body 144 (rather than into the upper supply bracket 56). Thus, water enters the transfer valve body 144 and is passed directly to the diverter stem 148.

In the second configuration illustrated in FIGS. 22-23 , the diverter stem 148 is modified to accommodate just a single pipe, instead of the first showerhead pipe 92 and the supply pipe 88. The supply pipe 88 and first showerhead pipe 92 are removed from the waterway assembly. The inlet connector 64 is modified to accommodate a single pipe 292. The single pipe 292 fluidly couples the diverter stem 148 to the inlet connector 64. In an alternative construction (not shown), the first and second showerhead pipes 92, 96 are coupled together to form a single pipe.

In another embodiment, shown in FIGS. 24-25 , the diverter stem 148 is modified to accommodate the first configuration (including the second cavity 216 coupled to the supply pipe 88 and the opening 178 coupled to the first showerhead pipe 92) and the second configuration (defining a second inlet 284 in the rear end (toward the wall W)). With this modified diverter stem 148, the shower bar system 20 can selectively be used with a high or low supply pipe P with minimal modification required by the installer (e.g., a single shower bar system 20 can be manufactured for use with either high or low supply pipes P).

In such a construction, when the shower bar system 20 is installed on a high supply pipe P, the installer closes the lower fluid connection of the shower bar system 20 (e.g., plugs the second arm 188 of the transfer valve body 144, or the second outlet 284) to inhibit water from leaking out of the escutcheon 172. When the shower bar system 20 is installed on a low supply pipe P, the installer closes the upper fluid connection of the shower bar system 20 (e.g., plugs the upper supply bracket 56 (the first cylindrical section 100, the second cylindrical section 104, etc.) to ensure that water does not exit the upper supply bracket 56 toward the wall W.

Instead of plugging the un-used fluid connection of the shower bar system 20, the shower bar system 20 may include a valve arrangement to prevent unwanted flow. For example, a check valve (not shown) may be provided for each fluid connection to allow incoming flow from the selected fluid connection (e.g., the high supply pipe P) and to prevent outgoing flow through the un-used fluid connection (e.g., the low supply pipe P). One check valve (not shown) could be disposed at a location between the second cavity 216 and the upper supply bracket 56 to inhibit water from exiting the upper supply bracket 56 when the shower bar system 20 is installed on a low supply pipe P and to allow water into the upper supply bracket 56 when the shower bar system 20 is installed on a high supply pipe P. Another check valve (not shown) may be disposed in or near the second inlet 284 or second arm 188 to inhibit water from exiting through the escutcheon 172 when the shower bar system 20 is installed on a high supply pipe P and to allow water into the second inlet 284 when the shower bar system 20 is installed on a low supply pipe P.

The shower bar system 20 described herein may provide several independent features and/or independent advantages. The shower bar system 20 may be installed into an existing shower from the shower area. The installer does not need to directly access the area behind the shower wall. In other words, the installer does not need to remove a portion of the wall sufficient for the installer to reach through and manipulate structure (e.g., the water supply pipe P, the connection to the supply pipe P, etc.) behind the wall. The installer only needs to make a hole in the wall W to accommodate the supply adapter 40 and the upper supply bracket 56 is necessary. Thus, the shower bar system 20 may be retrofitted into an existing shower easily and in a cost-effective manner, as compared to other shower bar systems.

The shower bar system 20 can be installed in showers that have walls of varying thickness. As described above, the supply adapter 40 is able to accommodate walls of different thicknesses. The shower bar system 20 can be installed in showers in which the shower wall W is offset from a wall where the water supply is accessed or in which the outlet of the water supply pipe is a varying depths. The shower bar system 20 can be installed in such locations because the supply adapter 40 is able, as explained above, to telescope into and out of the upper supply bracket 56, thus allowing the shower bar system 20 to reach the household water supply, regardless of depth behind the wall W, while maintaining the shower bar 26 in a vertical orientation.

The shower bar system 20 may provide the transfer valve assembly 30 in a location which is more accessible to users (e.g., because of the lower height of the transfer valve assembly 30). The illustrated shower bar system 20 transfers the load to the shower wall, not the water supply pipe P. Thus, the risk of damaging the water supply pipe P is minimized because pulling forces which may be transferred from the shower bar system 20 to the water supply pipe P are minimal. The illustrated shower bar system 20 may be able to withstand a pull force of 300 lbs. or more.

The tube-in-tube design of the shower bar 26 provides for greater flexibility of material selection for components disposed in the interior of the shower bar 26, such as the supply pipe 88, the first showerhead pipe 92, the second showerhead pipe 96, the inlet connector 64, etc. Various laws and codes limit the use of certain materials which may be exposed to the consumer directly or through the supplied water.

The shower bar system 20 may provide a handshower hose 264 that does not interfere with the shower on/off valve V. The angled hose connector 32 directs the handshower hose 264 around the shower on/off valve V, rather than on top of and/or against the shower on/off valve V (as is done by current handshower hoses), to avoid interference. The shower bar system 20 may provide a handshower 24 that is convenient and easy to use because the angled hose connector 32 swivels relative to the shower bar 26. Thus, the user is able to move the handshower 24 to different areas of the shower without having the handshower hose 264 bind on the shower bar 26.

The shower bar system 20 allows for the user to select a right-hand or a left-hand orientation. In the left-hand orientation, the handshower 24 is placed on the left-hand side of the shower bar 26, the bracket assembly 34 is turned to hold the handshower 24 on the left-hand side of the shower bar 26, and the angled hose connector 32 is swiveled to accommodate having the handshower 24 on the left-hand side of the shower bar 26. In the right-hand orientation, the handshower 24 is placed on the right-hand side of the shower and the bracket assembly 34 and angled hose connector 32 are moved accordingly. In some installations, it is desirable to select the right-hand or left-hand orientation due to obstructions on the shower wall such as, for example, soap holders, shelves, etc.
